13th September 2002:-

A small DPV (Aquazepp) was transported to Sump 2 along with 2 x 20litre cylinders.

100m of steel cable was also transported through. 8mm spits were placed at various points along the streamway after the canal, and a tight line was established from the end of the canal, all the way to the end of the streamway just before Sump 2. This was to facilitate the solo transport of a large Aquazepp following a dive in Sump2. As there were only 2 personnel on this expedition there was a good chance that one of the big aquazepps would need to be moved through the streamway when only 1 person was in the cave. This tight line proved extremely useful for this scenario, but in the situations where there are 2 or more persons available, it is far easier to transport the large scooters via the streamway bed.

Using an Inspiration rebreather, 2 x 20litre bail-out cylinders and 12litre nitrox bail-out, J Mallinson scootered to the end of the line at 1250m. A line reel which had been lost the previous year was found on route. Using fins, to conserve scooter battery power for the way out, the tunnel continued as large as before and at one point dropped to -60m, but soon rose up to the average depth of 50m again.

270m of new passage was explored to a point 1520m into the sump. A line survey was completed on the return to the scooter. 240 minute dive time.

A large Aquazepp scooter was transported to Sump 2 for an exploration dive the following day.

17th September 2002:-

The fast ride-on Aquazepp quickly transported J Mallinson to the 1520m limit, and the continuing passage was explored using the same scooter. 430m of new line was laid to 1950m at a depth of 55m. At 1800m on the return, the Aquazepp scooter stopped working, and whilst considering the long swim back to base, JM started to bash the side of the scooter tube with the Goodman handle on the HID light. This worked, and with a running scooter a relieved JM scootered back to base, minus a primary light source! The 220minute dive proved the worth of using the large fast Aquazepp in this sump. The problem encountered with the scooter was found to be the prototype handles which contain the magnet for the reed switch. The handles had slipped round the tube (which had compressed due to the depth) and the magnet was then too far away from the internal reed switch. All handles now are screwed in place so they cannot slip round the tube.
